\chapter{Units and Constants}

The basic units are cm for distances, g for (macroscopic) masses, 
and ns for times. 
Particle energies, momenta and masses are expressed 
in eV, eV/\(c\) and eV/\(c^{2}\), respectively.
For example, the electron mass is given in eV/\(c^{2}\), 
whereas the mass density of a material is given in g/cm\(^{3}\). 
The mass of an atom is specified in terms of the atomic mass number \(A\).
  
There are a few exceptions from this system of units, though.
\begin{itemize}
  \item
  The unit for the magnetic field \(\mathbf{B}\) corresponding
  to the above system of units  (10\(^{-5}\) Tesla) is impractical. 
  Instead, magnetic fields are expressed in Tesla.
  \item
  Pressures are specified in Torr.
  \item
  Electric charge is expressed in fC. 
\end{itemize}
A summary of commonly used quantities and their units is given 
in Table~\ref{Tab:Units}.
\begin{table}

The values of the physical constants used in the code are defined  
in the file \texttt{FundamentalConstants.hh}.

\chapter{Gases}

Table \ref{Tab:GasesMagboltz11} shows a list of the gases 
available in the current version of Magboltz. 
The star rating represents an estimate of the reliability 
of the cross-section data for the respective gas. 
A rating of ``5*'' indicates a detailed, well-validated 
description of the cross-sections, while 
``2*'' indicates a low quality, that is 
a coarse modelling of the cross-sections 
associated with large uncertainties.
